Great coverage with no hiccups

Tello is cheap, easy to use, and offers great coverage. Coming from a different provider where I would run into technical problems somewhat frequently, I've been using Tello for a couple of years now and it's been flawless.

Tello is one of the best cell companies!

Tello has been, and remains one of the best cellphone companies out there. Hands down. I love that they're a no frills, straight-to-the-point and get stuff done without robbing-you-blind type of company. That alone speaks massive volumes for them, especially nowadays. I have quite a few of my family members and their families and friends now with Tello. If there were anything I'd ask them to offer would be the simple, big button phones for seniors. Other than that, keep don't what you're doing and thank you!

great but expensive roaming

Everything has been great, especially with the eSIM which I could do over the web last year before travelling to the US. Working "over wifi" on my iPhone, even SMS text, is great when I'm not in the US. Payment (card, apple pay...) works fine. The only pain points: * the app UI is a little confusing sometimes (but not terrible) * Roaming in Europe is a bit on the expensive side. It only works in "Pay as you go" mode and 1 cent per MB is too 5 years ago.
